Filed under Paper Guide. The standard office copy paper weight is most commonly called â20 lb. bondâ. Standard office copy paper weighs approximately 10.0 lbs per 1000 sheets. When people talk about âoffice copy paperâ, theyâre referring to the types of paper that most people use for their printers and photocopiers at home/work.
My understanding is weight will vary with the bond rating of the paper. Standard is 20# bond so one ream would weigh 5# or a box of 10 would weigh 50#, 24# bond would weigh 60#/box.Citing how things work - .... 500 sheets of 20 bond paper with a size of 17 by 22 has a weight of 20 pounds.The manufacturer would cut a sheet that big into four letter-size sheets, so a 500-sheet ream of 20-pound bond paper weighs 5 pounds.y understanding is weight will vary with the bond rating of the paper. Standard is 20# bond so one ream would weigh 5# or a box of 10 would weigh 50#, 24# bond would weigh 60#/box.
